Patent CA-2363174-A1 (CA)
Inventor: MACCARONE WILHELM
IPC: G01K15/00
Filed: 2001-11-19
Abstract: The verification of accuracy of an IR thermometer is provided at any temperature in the range of -25°C to +100°C, preferably at the room temperature. The magnetic surface of a thermo-conductive mat of the present invention is applied to any metallic surface in a room.      The user waits to give the contact thermometer arranged on the mat time to reach thermal equilibrium, and then aims the beam of the IR thermometer at the black body target on the mat. The reading of the IR thermometer is then compared with the reading of a contact thermometer, which is attached to the mat adjacent to the black body target. The lightweight, portable, low-cost temperature verification mats of the present invention can be used for verification of IR thermometers in different customer environments, such as in industrial environments, and with retail equipment, or home appliances, including ovens and freezers, etc.

Title: Intraluminal stent graft
Inventor: COLONE WILLIAM M
IPC: A61F2/07
Filed: 2000-07-24
Abstract: An intraluminal device such as a stent graft is formed of a conformable ePTFE  tube and preferably a compressed self-expanding stent affixed to the tube. The conformable tube is made by a special process which insures that the tube is radially deformable up to a predetermined diameter without exceeding the plastic deformation limit of the tube. The stent has a relaxed diameter larger than the diameter of the expanded tube after insertion so that the tube is biased to a cylindrical shape. The process for making the tube involves progressively dilating a small diameter extruded tube until a desired diameter is achieved. The tube is then contracted on a small diameter mandrel by heating.

Title: Method and apparatus for particle agglomeration
Inventor: TRUCE RODNEY JOHN
IPC: B01D51/02
Filed: 2000-11-10
Abstract: Fine particles of dust and other pollutants in gas streams entering a duct (10) are agglomerated to form larger particles which are more easily filtered in downstream processing. Particles in successive portions of the gas stream are charged by an AC ionizer (14) with opposite polarity, and the gas stream is introduced into an Evase portion (12) to slow it down. Particles of different sizes have differential deceleration and therefore mix generally in the direction of flow, aided by vibrators (13), leading to agglomeration of oppositely-charged particles.

Inventor: DAVIS MICHAEL A
IPC: G01J1/18
Filed: 2000-11-13
Abstract: A method and apparatus for compensating for systematic error a wavelength measure device, providing values for the wavelengths reflected from fiber Bragg gratings (FBGs) being used as sensors. The invention uses a high-precision temperature sensing and measuring circuit to measure the temperature of a reference FBG. The wavelength reflected by the reference FBG changes with temperature in a known way and the temperature of the reference FBG must be measured to know what wavelength is in fact being reflected. This wavelength is then provided to a dynamic compensator, which also receives the wavelength of light reflected from the sensor FBGs, and adjusts the wavelengths of the sensors FBGs using a correction based on the correction required to adjust the wavelength of the reference FBG so as to agree with the wavelength in fact reflected from the reference FBG. The circuit uses a reference resistor, unaffected by temperature, and a thermistor, and measures bothresistances using the same exact circuit components by switching either the thermistor or the reference resistor in to the same temperature sensing and measuring circuit.
